Controlled Onboarding

One home shouldn’t need four energy apps.

See where your power comes from, where it goes, and what is driving your bill.

1app.energy brings supported solar, battery, EV and tariff data together, with battery protection during supported Octopus and EDF smart charging, plus Axle Energy export value for eligible homes.

Supported home setups

Built around the energy setup you already use.

1app connects to the hardware you already own - no new boxes, no rewiring. Onboarding focuses on the inverter, charger and tariff combinations where whole-home context is most valuable.

Best fit today

You run a supported Solis inverter, SunSynk beta monitoring, or another reviewed battery setup.

You want one clear view of solar, battery, EV charging, grid and tariff data.

You use a supported EV charger or tariff connection alongside your solar and battery.

You want visibility first, with supported controls enabled only when you choose.

Controlled onboarding is open for Octopus, MyEnergi/Zappi, Solis and supported tariff setups. Ohme and Hypervolt EV charger support is live where compatible. SunSynk monitoring and LuxPowerTek remain beta paths. Daikin heat pump access remains approval-pending. More integrations follow as approvals and support coverage deepen.

When energy apps work alone

Smart EV charging can quietly drain
the battery you meant to keep.

On some supported setups, daytime EV charging can draw from stored battery energy. Your charger, inverter, tariff and heat-pump apps can each show only part of the picture, making it harder to understand the whole home or coordinate a response.

Daytime charging can use stored energy

On some supported setups, a daytime EV session can draw from the home battery before you expect it.

Energy used at the wrong time
📱

Four apps, no whole-home view

Your charger, inverter and tariff screens each show one piece of the picture. It is difficult to see the complete flow in one place.

More switching, less context
☀️

Manual schedules are easy to miss

Battery modes, EV schedules and tariff windows can fall out of sync, leaving you to check and adjust them yourself.

More admin, more room for error
📉

Heating efficiency can be hard to see

When heat-pump data sits in another manufacturer app, changes in performance and energy use can be harder to spot alongside the rest of your home.

Higher heating use can go unnoticed

Why people start looking for a fix

Poor coordination can waste energy and increase cost. The impact depends on your tariff, battery and actual usage.

How 1app.energy helps

Protect your battery. See the whole home clearly.

1app.energy brings supported solar, battery, EV, tariff and heat-pump data into one view. For eligible homes, it can protect stored battery energy during supported smart charging and use cheaper tariff periods where controls are available.

We detect

Supported smart charging starts

1app.energy recognises a qualifying session and checks whether battery protection is available for your setup.

We protect

Battery protection responds where enabled

For eligible homes, 1app.energy can apply the configured protection response during the session.

We optimise

Use cheaper periods where supported

Where tariff data and battery controls are available, 1app.energy can schedule eligible battery charging in lower-cost periods.

Autopilot battery export

Turn spare battery energy into export value.

Autopilot checks the price, keeps enough battery for your home and exports only when it makes sense.

If you take part in Axle Energy events, confirm the event window. 1app.energy calculates its value from measured grid export and the saved reward rate, while Axle confirms eligibility and official payment.

Why renewable homeowners choose 1app.energy

Practical feedback from homes trying to make solar, battery, EV and tariff behaviour easier to trust.

Axle credits separatedBattery charge vs tariffEV impact on batteryDaily cost by source
Controls in one place
Everything is controlled flawlessly with full live visibility.

I use 1app.energy with Fogstar batteries, a Solis hybrid inverter, Zappi Glo and Octopus Go. The value is having battery charging, home coverage and tariff timing working from one clearer place instead of trying to line up separate apps every evening. It makes the whole setup feel easier to trust.

Carl Harvey
Carl's story
Solar + battery + grid
The Solis app gave me data, but not peace of mind.

I still found myself checking different screens, guessing what the battery was doing, and trying to work out the day manually. 1app.energy pulls the solar, battery, grid, home usage and tariff picture together. For a home with this much hardware, it feels like the missing software layer I expected after installation.

Solis battery homeowner
See if EV uses battery
The stressful part was never plugging in the car.

It was wondering whether the EV was quietly pulling from the battery, whether it matched the cheap-rate window, and what it meant for the rest of the house. 1app.energy makes the EV, battery and tariff behaviour easier to understand, and where supported, helps protect stored energy from the wrong kind of charging.

EV and smart tariff household
One live home dashboard
Well designed, takes a lot of the effort out of running a modern home.

A clear, reliable app for managing a three-phase home energy setup in one place. The value is seeing usage, battery and EV charging together on one dashboard instead of checking separate apps for each part of the system. It makes daily decisions feel less manual.

Mike's story
Axle credits stay separate
Axle Energy events were exactly the kind of thing I would have tracked in a spreadsheet.

Then I would have forgotten about it, or mixed it into normal export numbers. Having Axle credit shown separately from normal export credit makes the report clearer and saves me from doing my own manual maths after every event. It keeps the reward visible beside the normal export story.

See why cost changed
Before 1app.energy, I could see numbers, but not always the story.

Now I can see what came from solar, what came from the battery, what came from the grid, and how the home actually used energy. That breakdown makes the whole setup feel more trustworthy because I can understand why the day cost what it did, and what changed underneath the total.

Match battery to tariff
The battery used to feel like something I owned but did not fully control.

I knew it was charging and discharging, but not always whether it matched the tariff or the house. 1app.energy helps connect the battery behaviour with off-peak periods, EV demand and home usage, so I feel more confident leaving the system to do its job without checking it constantly.

Battery optimisation user
Stop switching apps
Once you have solar, batteries, an EV charger and a time-of-use tariff, separate apps become tiring.

Each one shows a slice, but none of them explain the home. 1app.energy gives the joined-up view I expected from the start. For me, it is a no-brainer because it makes expensive equipment easier to understand and use day to day.
